Title: Signal receiver for satellite broadcast
Inventor: KOISHO YOSHIJI
IPC: H01P1/10
Filed: 1990-04-18
Abstract: A signal receiver has probe antennas 2a, 2b provided in a waveguide 1 for receiving differently polarized waves eg both vertical and horizontal polarized waves. The probe antennas 2a, 2b are arranged in relation to intersect at right angles respectively in the waveguide 1, wherein each antenna 2a, 2b is connected to input terminals 10, 20 of an amplifier respectively. According to the structure, it is possible to receive both vertical and horizontal polarized waves simultaneously without using a rotational probe antenna. In a modification clockwise and anti-clockwise circular polarization waves can be received. The amplifiers may each include a gallium arsenic field effect transistor (4, 5 Fig 4) selectively switched on to receive the required vertical or horizontal polarized waves. <IMAGE>

Title: Control of air conditioning
Inventor: SAGA HIDEO
IPC: F24F11/00
Filed: 1991-04-02
Abstract: Air conditioning in a room is controlled in both an interior zone and a perimeter zone individually. Either a heating or a cooling mode is selected for each zone in accordance with a room temperature set point. The interior zone is controlled using its actual temperature and the set temperature to determine the interior zone operation mode inter alia, whilst the set temperature is also compared with the detected room temperature in the perimeter zone to determine the perimeter zone a operation mode. A correction to the set temperature for use in the perimeter zone is selected from predetermined values in accordance with interior and perimeter operation modes. Effects of variable passive solar heating, for example, can be counteracted thereby. <IMAGE>

Patent GB-2261709-A (GB)
Title: Pumps
Inventor: HODGSON DEREK FRANK ERNEST
IPC: F04B43/06
Filed: 1992-05-29
Abstract: A pump, especially for removing liquid from boreholes, comprises a housing (30) provided internally with a diaphragm (36) to define two chambers (38, 40). The pressure in one chamber (38) can be varied, for example by being connected to a compressor via a rotary valve. The diaphragm (36) is displaceable in response to pressure changes in said one chamber to effect movement of fluid through the device, e.g. in a pulsed flow. The pump can be used with noxious fluids as there are no working parts in contact with the fluid being pumped. In an alternative embodiment, a flat diaphragm (1, Fig. 1) is displaceable alternately into two chambers (9, 11, Fig. 1), so that the internal volume of the chamber into which the diaphragm moves becomes substantially zero. <IMAGE>
Patent GB-2258195-A (GB)
Title: Pneumatic tyre assembly
Inventor: HAMILTON ROBIN
IPC: B60C17/02
Filed: 1992-07-27
Abstract: A pneumatic tyre assembly 10 comprises a tyre 14 containing a flexible partition 16 which divides the space within the tyre 14 into an outer chamber 18 and an inner chamber 20. Valves 22, 24 allow air to be introduced independently into either chamber 18, 20. A change of pressure within one of the chambers may be at least partly compensated by a change of volume of the other chamber. This mitigates the effects of a puncture in the tyre 14, or a failure of either valve 22, 24. A pump 34 and a control circuit 30 may be mounted on the wheel to which the tyre assembly is fitted, the pump being actuated by rotation of the wheel, or the pump 34 and control circuit 30 may be mounted on a vehicle with which the wheel is associated. The control circuit 30 can transmit signals, for example to the vehicle driver, by mechanical, audible, electrical, radio or magnetic means to indicate the state of the tyre or to give an alarm. The control circuit 30 may also receive signals, for example from the driver, to cause a change of tyre pressure. <IMAGE>

Title: Determining cable phase
Inventor: ROY KEITH JOHN
IPC: G01R31/02
Filed: 1992-12-24
Abstract: An apparatus for determining to which phase an electricity power distribution cable belongs comprises a detector 11 for coupling to a selected outgoing distribution cable 8 from a sub-station or distribution centre 10 and a radio transmitter 12 for transmitting a phase-identifying signal modulated with the signal detected on the cable B. At a point 20 remote from the sub- station or distribution centre a detector 21 is coupled to the distribution cable X, and a radio receiver 22 receives and demodulates the radio signal. The receiver 22 includes a comparator which compares the demodulated signal with the signal carried by the distributor cable X to provide an indication of the difference in phase between the two signals. In an alternative arrangement, differently coded signals are injected onto the respective cables at the sub-station and a decoder at a remote point processes the signals from a detector to determine which of the coded signals are present on a cable. <IMAGE>
